Rachel is painting one wall of her room with a pattern of squares. she want to alternate between red squares with an area of 25 square inches and blue squares with an area of 16 inches.
part a: find the side length of each square. show or explain your work.
part b: if she has enough room to place 12 of each type of square with not space between them, how long is the wall? explain your reasoning.

Part A.  5 in and 4 in

Part B. 108 in

Step-by-step explanation:

Part A.  

A (square) = side², then side = √(A)

A1 = 25 in², then side1 = √(25) = 5 in

A2 = 16 in², then side2 = √(16) = 4 in

Part B.

12*5 in + 12 * 4 in = 60 + 48 = 108 in

length of the wall = 108 in

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
